Just because you have a BMS on board, don't think that your pack is protected.
Until you allow the BMS to shut down the charger, your pack IS NOT PROTECTED!

You MUST make sure that:

• When the BMS says "stop charging" the chargers does stop charging
• When the BMS says "restart charging" the chargers does restart charging.
• The BMS is powered whenever the vehicle is plugged in the wall (whether or not the charger is on at the time)

DO NOT SKIP THIS, or YOU WILL KILL YOUR BATTERY!

The BMS must be powered whenever the vehicle is plugged in the wall to protect the pack during charging, and to perform balancing even if the charger is off at the moment.

If there is any current in or out of the pack, yet the BMS is off, your pack IS NOT PROTECTED!

Near the end of charge, the BMS will turn the charger on and off, continuously, for a while.
You MUST allow the BMS to do that; otherwise, the BMS will not be able to balance the pack.

Just follow the instruction below, exactly, and you'll be fine.

You MUST use a fuse ("Charger fuse"), between the pack and the Lithiumate Lite master's "Charger current sensor" input, as close as possible to the battery.

The fuse must rated for DC operation, rated for the full pack voltage, and rated for the charger current (30 A maximum, else you may blow up the Lithiumate Lite's charger sensor input).

This charger allows both control options: AC power and DC control.

With this option, the BMS master controls the Brusa NLG4 charger through a contactor to switch the charger's AC power on and off.

AC power switching
NOTE: pin-out of 4-wire AC connector is for rev C Master. For rev F Master use pins 3 and 4 instead.

With this option, the BMS master controls the Brusa NLG4 charger through an input that disables or enables the charger.

No isolation relay is required.

Control input
NOTE: pin-out of 4-wire AC connector is for rev C Master. For rev F Master use pins 3 and 4 instead.
